It's no wonder it's called the Canticles of Canticles.
A couple of years ago, I attended a workshop given by a priest on Lectio Divina, an ancient way of reading and meditating on the Scriptures. He asked us, "which book of the Bible is the lens through which every other book can - and should - be read?" We guessed - "is it Genesis?...Revelation?..." "No," he said. "It's the Song of Songs." The older I get and the more often I contemplate Solomon's Song, the more I see the truth in this.
"I slept, but my heart was awake.
Hark! my beloved is knocking.
'Open to me, my sister, my love,
my dove, my perfect one;
for my head is wet with dew,
my locks with the drops of the night.'
I had put off my garment,
how could I put it on?
I had bathed my feet,
how could I soil them?
My beloved put his hand to the latch,
and my heart was thrilled within me.
I arose to open to my beloved,
and my hands dripped with myrrh,
my fingers with liquid myrrh,
upon the handles of the bolt.
I opened to my beloved,
but my beloved had turned and gone.
My soul failed me when he spoke.
I sought him, but found him not;
I called him, but he gave no answer.
The watchmen found me,
as they went about in the city;
they beat me, they wounded me,
they took away my mantle,
those watchmen of the walls.
I adjure you, O daughters of Jerusalem,
if you find my beloved,
that you tell him
I am sick with love."
- The Song of Solomon 5: 2-8, RSV
